How do I write this problem?
to receive a grade B in a math course, you must have a mean of 83 on five tests (4 tests + one final) all 100 pts maximum each. Your scores thus far are 85,79,82,and 81. How many points must you have on the final, to earn the B? write down your work..

math 
Ms. Sue,
0.83 * 500 = 415
You need a total of 415 points.
Your test grades so far = 327
415 = 327 = 88
You need at least a score of 88 on the final.

Ms. Sue,
You're welcome.
I just noticed that I have a typo:
415  327 = 88
